DAVID D. LORD, OF COLORADO SPRINGS, COLORADO.

ORE-CONCENTRATOR.

SPECIFICATION forming part of Letters Patent No. 612,742, dated October 18, 1898.

Application filed October 1 3, 1 8 9 7.

T0 aZl whom. it may concern:

Be it known that I, DAVID D. LORD, of (1010- rado Springs, in the county of El Paso and State of Colorado, have invented a new and Improved Ore-Concentrator, of which the following is a full, clear, and exact description.

This invention relates to concentrators for separating precious metals or other metals from ore or other foreign matter; and the object is to provide a device of this character in which the separation may be quickly and thoroughly done at a comparatively small expense for operation.

I will describe an ore-concentratorembodying my invention, and then point out the novel features in the appended claims.

Reference is ,to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all'the views.

Figure 1 is a side elevation of a concentrator embodying my invention. Fig. 2 is a front end view thereof. Fig. 3 is a section, on the line 3 3 of Fig. 7, of a concentrator-plate-carrying car used in the apparatus. Fig. 4 is an edge view of certain connecting-plates employed. Fig. 5 isa front view thereof. Fig. 6 is a sectional elevation of the forward portion of the concentrator. Fig.7 is a plan view thereof. Fig. 8 is a side elevation of a distributing-head employed, and Fig. 9 is a sectional elevation of the rear portion of the concentrator with the intermediate section re-. moved and the trough connecting the upper section with the lower section in operative position.

The body portion of the concentrator comprises a receiving-section 1, a removable secat opposite sides with vertical lifting-bars 7,

$erial No. 655,062. (No model.)

which are connected to a cross-head S,attached to the pistons of hydraulic jacks 9.

.14, attached to a cross-head 15, operated by hydraulic jacks 16.

The section 3 has a series of fixed plates 17' for receiving material from the plates 13, and between the plates 17 and 13 are narrow plates 18, that may be moved upon the plates 17, so as to disengage them from the removable section, whereby said removable section may be disconnected from the apparatus. row plates 18 are secured at their ends to vertical bars 18, which, with the plates, form a frame designed to slide between the side boards of the section 3. When in operative position, the plates 18 are locked to the movable section by clips 18. The bars 18 are supported on a base 18, which has its top inclined. l

Mounted to rotate in the section 3 is a drum 19, closed at its ends and having a series of plates 20 extended from its shaft to its periphery and from end to end, whereby radial pockets are formed in said drum.

Mounted on a shaft 21 below the drum 19 are deflector-plates 22 and 23, designed, in conjunction with a stop-plate 24, extending below the drum, to direct the heavier and more valuable particles discharged from the drum to a suitable receptacle by means of a which material that may be thrown with considerable force from the upper plates 17 will strike and be directed into the pockets in the drum. 7

It will be noted that the plates of the sev eral sections 1, 2, and 3 are arranged progress The narively closer to each other from the top downward.

Forward of the section 1 is an ore-receiver 27, separated from said section 1 by means of a vertically-movable gate 28. This movable gate at its lower end engages against the outer side of a trough-shaped base 29 at the bottom of the receiver 27, and the said gate is provided with a passage 30 for the discharge of the heavier particles in large quantities from the receiver 27. (See Fig. 6.) Said discharge will be received by-a trough 31 (see Fig. 1) and conveyed to any suitable place. The gate 28 may be raised or lowered by means of a connection 32, (see Fig. 6,) with a sprocketchain 33 extended over sprocket-wheels 34 and 35, and to facilitate an easy operation of said gate the stretch of the chain 33 opposite the connection 32 will be provided with a counterweight 36. '(See Fig. 1.)

Arranged in the lower portion of the receiver 27 is a cylinder 37, (see Fig. 6,) having a series of longitudinal chambers 38, 39, 40, and 41. let consisting of a slot 42, extended the full length of the cylinder within the concentrator. The several chambers 38 to 41, inclusive, receive in their opposite ends short pipes 43, and these several short pipes 43 connect with ports extending through distributing-heads 44, mounted to rock on pillow-blocks 45. The ports through the distributing-heads each communicate with a water-pipe 46, and each of these pipes 46 is provided with a valve, so that water may be discharged into one, two, three, or all of the chambers in the cylinder 37. The distributing-heads 44 have swinging connection with said pipes. Rocking motion may be imparted to the cylinder 37 in any desired manner. I have here shown it as provided at its ends with gear-wheels 47, with which racks 48 engage. (See Figs. 7 and 8.) The said racks may be operated by hydraulic or any other desired power.

The base 29 of the receiver 27 (see Fig. 6) has an opening extended lengthwise of it at its center, and movable vertically in this opening is a hollow bar 49, having feed-pipes 50 (see Fig. 2) for supplying water thereto. Supported by this hollow bar 49 is avalve 51, (see Fig. 6,) having its stem portion extended downward into said bar, and at the side of said stem portion are ports 52, through which water may be discharged into the receiver when the valve is raised. This valve 51 has its opposite side edges at the lower side beveled downward and inward to engage upon the inclined wall of the base of the receiver. The hollow bar 49 and the ports 52 communicate with a hollow boxing 53, and the said bar and valve are raised and lowered by means of a screw-shaft 54, (see Fig. 2,) having bearings through the supporting-legs of the concentrator. This screw-shaft 54 is provided with right-and-left threads engaging with blocks 55, from which links 56 extend to a swiveled connection with the boxing 53.

Each of these chambers has an out-- The hollow boxing 53 at its lower portion is provided with a slide-valve 57. (See Fig. 1.) At the front and rear of the hollow boxing 53 are other hollow boxings 58 and 59, each provided with a slide-valve at its lower portion, and above the valves 57 and 60 are slide-valves 60. These several slidevalves may be opened when it is desired to discharge material received in the hollow boxings. The hollow boxings 58 and 59 communicate, respectively, with ports 60 and 61, (see Fig. 6,) leading through the base 29 at the sides of the ports 52, and these ports 60 and 61 are controlled by swinging valves 62 and 63. These valves 62 and 63 are rounded at their lower sides and are seated on movable bars 64, with which screw-rods 65 engage,these screw-rods being extended through tapped holes in the base 29, and by manipulating these screw-rods 65 the valves 62 and 63 may be adjusted. The upper inner edges of the valves 62 and 63 are designed to engage an inclined portion of the base 29 at the upper ends of the ports 60 and 61, the said inclined portions forming valve-seats. The valves may be raised and lowered relatively to the valve-seat by means of eccentric-rods 66, passing longitudinally through the base portion of the receiver. The ecceritric-rods have cranks 66 on their outwardly-extended ends, and from these cranks operating-rods 66 extend. (See Figs. 1 and 2.)

Extended longitudinally through the side of the base 29, against which the gate 28 slides, is a waterway 67, having an upwardly-inclined opening 68, (see Figs. 6 and 7,) through which water may be discharged to prevent sand from entering between the outer surface of the base 29 and the surface of the gate 28, engaging therewith, thus preventing any undue friction, and the same method will be adopted as to the other similar surfaces and joints in the receiver 27, where the sand would otherwise enter. 4

Referring now to Fig. 1, arranged underneath the drum 19 is a water-pipe 69, having a longitudinal slot at its upper side. This water-pipe 69 is mounted to oscillate back and forth, so that water forced through the slot may wash the plates 20 of the drum. The oscillating movement of this pipe, which may be produced by any suitable means, will facilitate the washing, as the water will be evenly distributed by such motion.

Pivotally connected to the side walls of the section 3 at its top is a trough 70, designed to connect the top plate of the section 1 with an overflow-chute 71. This trough 70 is designed to be used when the section 2 is removed for cleaning or for giving free access to the plates of the other sections. The overflow from the receiver will be directed to the drum 19 by a deflector-board 71. The upper end of the trough 70 is attached to chains or ropes 72, extending over pulleys 73, mounted to rotate on a shaft supported by a frame consisting of sections 74, extended from the cas= in g 1, and a section 75, extended from the section 3. These chains or ropes 72 extend over pulleys 76 and have counterbalance-weights 77 at their ends.

In'operation the receiver 27 will be about half filled with water, and then the oresay from five to ten tons-in a crushed state will be placed in the receiver. Water is then 'injected into any one or all of the chambers in the cylinder 37 and is forced out of said chambers through the slots. 42. This water Will be forced up through the descending sand, forcing back the lighter particles, the heavier particles dropping down to the lowest point in the base of the receiver, and byliftin g or lowering the Valves 62 63 the same will descend still fart-her, to be caught above the valves where the values may. be obtained. The valves 62 63 may be slightly open during the whole time of the operation to expedite the catching of the values. Byraising. the valve 51 water will be discharged into the receiver 27. The amount of foreign particles caught at the base of the valve 51 with the metallic sand will govern the operator as to the amount and force of water to housed.

These manipulations may be varied to suit the operations. Instead of forcing the water up through the sand the sand may be allowed to settle on the bottom of the receiver. .When it all settles, water is then discharged in the chambers of the cylinder 37, at first with greater pressure in the lower chambers, which will force the lighter particles and, if desired, the heavier particles upward, or the cylinder 37 may be dispensed with, the sand being forced back and up by raisin g the valve 51 to allow the water to enter the receiver 27 at any desired pressure. By rocking the cylinder' 37 back and forth the water will be evenly distributed. The valves 51, 62, and 63 may be all raised at the same time, so that the heavier sand may drop into the boxings 53, 58, and 59. When all the valuable particles that can in a reasonable time be precipitated have been deposited in the bottom of the receiver 27, then the gate 28 is to be lowered by means of the chain 33 and'a mixture of light sand and water flows over the top of said gate and over the several plates to the drum 19. The heavier particles of the sand that passes over the plateswill fall through the slots of the upper plates to the plates be low. At difierent intervals the top plates 5 and 13 willbe raised by means of the hydraulic jacks, so that the plates below them may be flushed with water. This flushing may be done by a series of water-pipes connected together at one end and extended through holes 78 and entirely across the section 1 of the apparatus.

In order to more quickly draw off the heavy particles from the receiver 27 and also to empty said receiver of all particles not intended to pass into the boxings 53, 58, and 59.

and over the plates, the gate 28 may be raised until the opening 30 through the same has its upper end above the wall of the base 29. The material may then discharge into the trough 31.

When gold ores are to be concentrated, the plates 5, 13, and 17 will be amalgamated'on their upper surfaces, but the plates 20 will betruck will be moved lengthwise of the amal-.

gamator, carrying the movable section and moving the plates 18 over and upon-the plates 17. Then by releasing the clips 18' the truck may be moved back and the movable section may be rolled out on either of the side tracks 80. (See Fig.
